## Description

Product Description

Review: 5 stars. - Great sound quality, long lasting battery, easy to charge, great quality and comes with spare ear buds. Easy to connect, and just overall great! Definitely worth buying.
Review: Great value earbuds - I've had several different brands of earbuds, these hold a place of their own. Firstly: Their battery life will last forever many hours. I've used them upwards of 7 hours straight without dying. The case power life can go days without needing to recharge from multiple uses. Sound quality isn't quite BOSE but does deliver clear quality. One downside in my opinion, although given various size rubber ear cones I struggle to find one comfortable to fit my ear, maybe the shape, or maybe my ears. All in all excellent value for the price.
